FIELD: measuring equipment engineering, possible use in radio engineering for passive detection and space-frequency-time localization of complicated signals.
SUBSTANCE: increased efficiency is achieved due to additional information extracted from two-dimensional time-frequency discrepancy function, which is formed and transformed to function of mutual spectral density for each expected arrival direction for signals, coherently received by two spatially distanced channels.
EFFECT: increased efficiency of localization of several complicated signals with a priori unknown form and frequency-time structure in broad sector of angles.
